BMW Audio System Failure $8 FIX! SOS Malfunction!

A little while ago the audio system along with some other small electronic issues arose and it was frustrating to say the least. Here's how I fixed it all with one little part costing only $8.

It be nice if you can show a video on how to install it!

[@gerrygalvan7313]

And show the problem and if it did get fixed.

[@kennyr.8183]

This worked for me as well about a year ago. It's just not the same car without music :)) Great video !

[@carasam6551]

Worked perfect and I didn't have to trim anything on the adapter with the link you gave. Took me 15-20 minutes total and $13 . Thank you so much!!

[@SimplyCarThings]

no problem man! glad you got the issue resolved!

[@abushukriah]

Dude I removed the plastic around the plug in and presto it worked! Once again the KZbin car gods have spoken and saved me $$$$$$ on repairs, thanks!

[@SimplyCarThings]

glad the video was able to help you man! Thanks for watching!!

[@SimplyCarThings]

Some of the footage where I showed how to connect the cable in this video was corrupted unfortunately so i didn't have much to work with. However, if your audio system is out here's how to fix: 1. Remove connector from Satellite Radio module (red/green/black cables) 2. Insert optical bypass loop into the removed connector 3. Voila! Done!

[@nateonfireball]

Simply Car Things did this also fix your satellite radio? My car has all the symptoms you named. I’m going to try and do this fix and get my Bluetooth working again and my auxiliary port working. Also do you happen to know of the directions are the same on an E60 535i?

[@BlackLabel67]

You forgot to show "where" that connector fits. Once you opened the trunk you described the parts but didn't point out where it is? Would you please? Thanks for sharing!

Any chance you can make a video showing us exactly where to plug this thing in at? I bought the one in the link, but not sure which cable to pull and plug this in at. We have the same car, it would be exact for me.

Nice video, I got the exact same problem on my 330 E91 2008. I have to try it out, but I'm convinced this will solve my problem too. Thanks again for the video 🙂

My audio started cutting out and crackling a couple weeks ago. I disconnected the amp and cleaned all the connections and now it works perfect. Hasn't crackled since.

[@marcodelsalto5592]

Did u also have the sos warning light

[@JaimeDRios]

You didn’t even show how to plug that bypass..

[@lovehatredshandog]

Ahh yes the brains a good thing to use lol

[@mxracingunlimitedltd7784]

It is a bad Sat Radio Module. The fiber optic audio setup is used to take advantage of its advantages like better sound and fast speed for data, but bmw used it only for the audio and some audio/Navi information. It is one loop from start to finish. A module is placed INLINE with the loop, and therefore breaks the loop and so the output is fed back out to the fiber again thru the modules output side. So if you just unplugged the Sat radio module, you would be breaking the loop. (Which is what the bad module does when normally plugged in to cause your issue). So you.must use this piece to loop the input back out to the output so it can make its way back to the main Audio Head Unit (idrive & non idrive). The HU is the start and the end of the "circular loop" around the car. The loop bypass its fiber optic connection to the defective Sat Module and fixes your issues bc now the Sat Radio module is not in the fiber loop anymore. You also will not be able to listen to Sat Radio anymore, if you did. This fix can also be done the oem way as well plus its free. It is alittle more time involved and slightly complicated, but it requires no extra parts and there are plenty of DIYs dealing with the fiber loop distribution block or sometimes called fiber add-on point. You just need to take DS rear side panel, right by where your left shoulder would be if you were sitting in the back DS seat, you will find the fiber ring distribution block. What you would do is take the Sat radio out of the fiber loop by unplugging the fiber wire running to it for input and re routing directly the output. The fiber optic cables plug in to the block. There's pics and diy's online. For example if you have an older idrive and you are upgrading to the newer cic, and you have 2 modules in the trunk like in the video, one must be removed. The cic uses one module for usb/bt/aux/internet/etc, while the CCC would require 2 modules(TCU & MULF2). So therefore you would get to behind the seat side cushion and rearrange the fiber lines properly. The black shielding around the fiber indicates one side of the loop and the bare green fiber optic cable represents the other side of the loop. Good video I'm sure this will help a lot.of people with the same problems. The Sat module is a common part to go bad and is 1k$+ new and pricey used. Most of the time water in the trunk is to blame, but not the sole reason.

[@AldrinHartunian]

Thanks for the video. I have that problem on my 2008 550i. Where do you connect this adapter though?

[@KennethBostonian]

My GOD this just happened to me last week. I knew it wouldn’t call, so I pressed the SOS button. It’called and locked everything out. Then I canceled the call, and audio and Bluetooth came back. This is just crazy. I’m going to bypass. Thank you for the video.

[@SimplyCarThings]

No problem glad it was able to help you!

[@wlnash]

Could you add the link to the part again?

[@tyjames5792]

I own a 2017 bmw 330i Xdrive. My sound and chimes all work on my car but sometimes the SOS error pops up and the goes away. It can be there for a few mins then it goes away. It can go days to weeks and then pops up. Any suggestions on how to fix And remove this error?

im going to try this. I already replaced the TCU and my satellite radio is coming in tomorrow. My radio works but no bluetooth or nav/ sos.

Where do you plug it in though what kind of video shows you what's wrong with it but doesn't show you where to plug it in

[@yzhan7684]

I had the problem on my X1 F48 2017 model. Assume it’s software have bugs. Tested to call SOS after shows SOS system failure message, get through perfectly, which proves the system NOT failure. Used voice control coincidentally last week, the fault message disappeared dramatically, and didn’t back till today. I rarely use voice control before, have tried to disconnect blue tooth device and reconnect from other youtube video, didn’t work well. Can’t say it’s the solution, but cost nothing and worth a try.

[@pabloperezsanchez-urdazpal7167]

Hi! Sorry to revive this subject. I have a very similar problem, only my audio system does work while reversing or opening the doors. Do you think this bypass fix would work? Thanks!

[@glencandle1772]

I’m having the same SOS and Bluetooth issues in my X5 E70, but I still have all the car chimes. Is my problem different?

My SoS call failure comes up and then my microphone won't work, so others can't hear me if on call or if I try to use voice commands. Do you think this would help? Thanks
